ABSTRACT:
An acoustical phased array having improved interaction efficiency and efficiency-bandwidth product. The array includes a body of acousto-optical material having one face grooved to form a number of sets of plane parallel surfaces, each set having n different height levels, where n is at least two. An electro-acoustic transducer is affixed to each surface and high-frequency signals are applied to the respective sets of transducers, each signal being phase-displaced by the same amount with respect to the signal applied to an adjacent set. The incremental height difference is 1
of the phase difference between signals applied to adjacent sets, expressed in wavelengths, and this results in elimination of one lobe of what would otherwise be a twin-lobe far-field acoustic radiation pattern, and an approximate doubling in interaction efficiency.
